Abstract
The utility model discloses a gate valve apparatus used for a ventilating duct. The gate valve apparatus comprises a valve body; a flashboard arranged inside the valve body and shaped like a roller shutter; a performing mechanism disposed at one end inside the valve body; a driving shaft connected with one end of the flashboard; a driven shaft connected with the other end of the flashboard via a rope; and a transmission mechanism connected with the driving shaft and the driven shaft. The performing mechanism and the driving shaft pass through a sidewall of the valve body. The driving shaft is connected with the performing mechanism. The performing mechanism drives the driving shaft to rotate clockwise or anticlockwise to pull up and open the flashboard. The performing mechanism drives the driving shaft to rotate anticlockwise or clockwise, and after the driven shaft is driven to rotate through the transmission mechanism, the driven shaft pulls the flashboard through rolling of the rope to close the flashboard. The flashboard is embedded in the valve body and will not interfere other devices when being opened and closed, thereby effectively solving sealing and space restriction problems of a gate valve.
